Statistical Operations: Analysis of Health Research Data is the successor volume to the authors' 1992 text Statistical First Aid: Interpretation of Health Research Data. Whereas the earlier book aimed at providing the "consumer of the health research literature" with "the level of statistical knowledge necessary to interpret the analyses that are most frequently used in [that] literature," the objective of Statistical Operations is to equip readers to carry out their own analyses. Some of the advanced topics and techniques addressed include Bayes' theorem (the authors are clearly sympathetic to the Bayesian school of statistical thought), examination of the validity in a given experimental situation of the mathematical assumptions underlying a planned statistical test, estimation of optimal sample size, interval estimation, construction of multivariable models, and such procedures as sequential analysis, stochastic curtailment, repeated measures analysis of variance, Cutler-Ederer life table analysis, and small-sample exact tests. Included with the book is
